Design groups

Design Group II

Of the 364 types on this site, 77 are in Design Group II, the band from 49 to under 79 ft of wingspan or 20 to under 30 ft of tail height. Cessna accounts for 16, Beech for 9 and Embraer for 7; 45 come from other makers. By engine type: 43 jets, 28 turboprops and 6 piston aircraft. Wingspan alone decides the group for 51 of them; for the other 26, the tail height lands in the same group too. Spans run from the Aero Commander 560 up to the Gulfstream IV.
